Abstract

Agronomy and agrochemistry have reached a level where further progress is neutral in relation to yield. Scientific progress helps environmental needs. Genetics alone may close the yield gap by a combined application of classical techniques and molecular knowledge. Large-scale genome analysis and related technologies provide access to a refined understanding of the genome. Fortunately, molecular markers are a genetic tool accepted by the public which often judges gene technology critically. There is a strong tendency that classical combination breeding together with marker assisted selection is more effective in achieving complex breeding goals than gene transfer approaches. Here, tools will be elucidated such as higher efficiency in parent selection; controlled combination of heterocygous parents; uncovering a rare but desired genotype in a large segregating population; or pyramiding single traits to result in more complex characters, e.g. durable resistance. Such techniques allow more reproducible and faster development of new and better cultivars. Today a breeder has to know how such modern breeding tools work and how to use them in an intelligent manner.
